Add Text to Video Online
This add text to video tool overlays a line of text on a clip — with full Vietnamese diacritics, since the text is drawn with the browser Canvas. Choose the size, colour and position (top/centre/bottom).
Processing runs inside your browser with ffmpeg.wasm, so nothing is uploaded. The text has a subtle outline so it reads on any background.

FAQ
Do Vietnamese diacritics break? No. The text is drawn with Canvas, so diacritics render correctly.
